RAILWAY BRAKE BEAM.

Application filed June 6, 1923. Serial No. 643,626.

To all whom z't may concern: edge portions of the bar, reversely disposed,

Be it known that I, SETH A. Gnome, a citiapproximately triangular, sections which fizen of the United States, and a resident of nally become the aforesaid arms constituting East Orange, in the county of Essex and portions of the truss-rod seat and extending 55 6 State of New Jersey, have invented certain above and below the middle portion of the new and useful Improvements in Railway truss-rod, and Brake Beams, of which the following is a Fig. is an edge view of the same. specification. In the drawings 10 designates the strut, 11

The invention pertains to trussed brakethe compression member and 12 the tension 1 beams for railway cars and especially to a member comprising a trussed brake-beam novel strut interposed between the compresfor railway-cars. sion and tension members of the beam. The strut is formed from a single bar of One purpose of the invention is to pro forged metal folded at its middle portion Vide in a single folded or tied forged metal into approximately Ushape having parallel 635 5 bar, a novel one-piece strut having at the sides 13, 14 and members, as 15.; for illustrafrontend thereof a seat, integral with the tion, at the free ends of said sides to engage strut, to receive the middle portion of the the compression member, which may be of tension member of the beam and also havany suitable cross-section.

The foIding or Using of the bar leaves thetra'nsverse "fold-end thereof rounded or convex onits outer surface, with the sections 20, 21 projecting from diagonally opposite corners of said end. 7

The folded bar is then subjected todies to form the c oncave seat 17 hereinbefore described and bend the cut sections 20, 21 forwardlyat the upper, and lower sides of said seat to constitute the reversely extending arms 18, 19.

In Figs. 2 and 3, the surface 25 is that which is leftafter the arm1$ has been cut and bent forwardly at the forward end of the strut, this surface in edge view also be ing shown at in 1. In Fig. 1 the dotted line 26 denotes the normal outer edge of the side member 1316mm which the arm 18 was cut and bent forwardly leaving the exposed surface25. y

In Figs.) and 2, the surface 27 is that which is left after the arm 19 has been, cut andbent forwardly at the forward end of the strut. Fig. 1 the dotted line 28 .denotes the normal outer edge of the side memberld from ,which the arm 19 was cut and bent forwardly, leaving the exposed ,The seat 1'(is convex'ed horizontally, as indicated the dottedline in Fig. 3, to reee'iye the curve d middle portion of the horizontal trussflod and said seat is concaved on yei tical lines to receiv e. the vertical conx ur aqelef sa i Informing the seat l'ion the fold-endof the bar I bend forwardly the sections 20, 2l to forrn the final arms 18, 19 and at the same operation bend forwardly on curved lines those transverse diagonally opposite portions of u'ie'fomsad of the bar which ar imm dia e y a ia i a i or rectly carry the inner and broader ends of the sections 20, 21 and henee th'eIse'at is fprmed in partby concaving forwardly diagonally opposite earner portions of the fol -9 d f the ar and in part by, at the same operation, setting the sections 20, 21

forwardly and inwardly to form the arms 18, 19. The treatment just described ofthe fold-end of the bar results in the formation of a truss-rod seat of exceptional efficiency and in the arms 18, 19 and adjacent portions of the end of the strut having a maximum horizontal extension along the upper and lower sides of the truss-rod, as shown in Fig. 2, in which it may be seen that the arm 18 extends across the longitudinal plane of the strut-side 13Iand that the arm 19 correspondingly extends across the longitudinal plane of the strut-side 14. In Fig. 3 it may be seen that the arms 18,19 point in opposite directions and retain their tapered 01 approximately triangular outline and that said bars are caused to extend laterally from the fact that the adjacent transverse portions of the fold-end of the bar carrying said arms are turned forwardly and inwardly on curved lines, thereby turning said arms to present their outer side edges forwardly. p

Inthemanufactureof the strut, my experience is that the flat bar should be subjected to the step indicated in Figs. 4 and 5, and then folded or U-ed and that the seat formation at the forward end of the strut should be formed on the folded bar by a single operation, as distinguished from U-ing the bar and forming the seat by a single operation.

What I claim as invention and desire to secure by Letters Patent, is:
